01
Sichuan-Qingdao Railway into the yellow section
On May 11, a breakthrough was made in the last control node project of the Chenghuang section of the Sichuan-Qingdao Railway - the Desheng Tunnel was completed in its entirety. The tunnel was designed by the Second Institute of China Railway and constructed by the Second Bureau of China Railway and the 16th Bureau of China Railway.
Southwestern Railroad
The builders fought for nearly ten years on the western Sichuan Plateau at an altitude of nearly 3,000 meters, and finally overcame the problem of large deformation of soft rock and created an engineering miracle.
The breakthrough of the Desheng Tunnel marks the completion of the Chenghuang section of the Sichuan-Qingdao Railway, and it is expected that Chengdu to Jiuzhaigou will achieve direct EMU within this year.
02
Chengdawan high-speed railway
At the construction site of the 350 km/h Chengdawan high-speed railway, a number of projects are progressing steadily. The Huayingshan Tunnel, a key control node project of the whole line, has completed 83.5% of the overall progress.
At the construction site of the Suining Fujiang Bridge, the side span and the main tower are being constructed simultaneously. At present, 40% of the progress of the Fujiang Bridge has been completed, and it is making every effort to sprint to the goal of capping the two main towers of the Fujiang Bridge at the same time in September this year.
At the construction site of the reconstruction and expansion project of Nanchong North Station, nearly 100 builders worked hard. "Now is the critical period of the project, we are stepping up the construction of the national highway G212 bridge pile foundation pier column and cast-in-place beam support, and strive to achieve the G212 bridge opened to traffic at the end of this year!" He Dangxuan, deputy manager of the Nanchong North Station project of the 12th Bureau of China Railway, said.
03
Chengdu-Xining Railway
The vision is cast on the western Sichuan Plateau, between the mountains and the reckless mountains, and the construction of the Chengdu-Xining railway is also steadily advancing. In the Kaharqiao Wetland Nature Reserve in Ruoergai County, Aba Prefecture, the construction of the Mamoko No. 1 tunnel is accelerating.
With an average altitude of more than 3,500 meters, the construction of Mamoko Tunnel No. 1 is complex, and the construction is facing many difficulties. In order to speed up the construction progress, the builders used large-scale equipment such as intelligent hydraulic inverted arch trestle, intelligent paving trolley, and intelligent lining trolley to run out of the construction "acceleration" by means of informatization.
"The project is a key control project on the girder channel, and there are strict requirements for the construction time node." Wan Binghong, commander of the Xicheng Railway of the 25th Bureau of China Railway, said.
04
West-Chongqing high-speed railway
At present, the entrance excavation of the Wubiao Yunguancun Tunnel in front of the Kangyu section of the West-Chongqing High-speed Railway has reached 1,230 meters, which is the first tunnel in the single excavation volume of the main tunnel of the whole line.
The total length of the tunnel is 6215 meters, the surrounding rock is mainly sandstone and mudstone, three places through the shallow buried gully, the maximum excavation section is 154.13 square meters, the maximum buried depth is 689 meters, the rock mass is broken, and the lithology is poor.
The construction introduces intelligent mechanical tunnel construction equipment such as 36-meter self-propelled hydraulic inverted arch trestle, intelligent pouring two-lining trolley, wet spray manipulator, etc., and monitors and manages tunnel facilities and equipment through the cloud intelligent command center.
05
Chengdu-Chongqing Central High-speed Railway
Drilling rigs, loaders, gantry cranes and other machinery are lined up, and construction personnel are racing against time...... At the site of the Chengdu-Chongqing Middle Line High-speed Railway Expansion and Renovation Project at Chengdu Station, the builders of China Railway Eighth Bureau started the accelerated construction mode.
It is understood that the Chengdu Station Expansion and Renovation Project, as a key project of the Chengdu-Chongqing Middle Line, will become a comprehensive transportation hub integrating a variety of transportation modes after completion.
At that time, Chengdu Station will effectively integrate various transportation resources such as intercity high-speed rail, urban railway, subway and urban bus to add convenience to passengers' travel.
